SAFETY
INSTRUCTIONS
SAFETY CHECK AFTER SERVICING
Confirm the specified insulation resistance between power cord plug prongs and externally exposed parts
of
the set
is
greater than
10
Mohms, but for equipment with external antenna terminals (tuner, receiver, etc.) and
is
intended for
[g
or
[Al,
specified insulation resistance should be more than 2.2 Mohms (ground terminals, microphone jacks, headphone
jacks, line-in outjacks etc.).
PRECAUTIONS DURING SERVICING
I. Parts identified by the
Lt
symbol parts are critical for safety.
Replace only with parts number specified.
2.
In addition to safety, other parts and assemblies are specified for conformance with such regulations as those apply-
ing to spurious radiation. These must also be replaced only with specified replacements.
Examples: RF converters, tuner units, antenna selector switches,
RF
cables, noise blocking capacitors, noise block-
ing filters, etc.
3.
Use specified internal wiring. Note especially:
I) Wires covered with PVC tubing
2)
Double insulated wires
3)
High voltage leads
4.
Use specified insulating materials for hazardous live parts. Note especially:
I) Insulation Tape
2) PVC tubing
3) Spacers (Insulating Barriers)
4)
Insulation sheets for transistors
5)
Plastic screws for fixing microswitch (especially in turntable)
5.
When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.), wrap
ends
of
wires securely about the terminals before soldering.
6.
Observe that wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
7.
Check that replaced wires do not contact sharp edged
or
pointed parts.
8. Also check areas surrounding repaired locations.
9. Use care that foreign objects (screws, solder droplets, etc.) do not remain inside the set.
10. Voltage Conversion
l)
Models for Japan, Canada, USA, Europe,
UK
and Australia are not equipped with this facility.
Each machine
is
preset at the factory according to destination, but some machines can be set to l
IOV,
120V,
220V
or
240V as required.
IfVoltage conversion on your machine
is
possible,
1-1)
Disconnect power cord.
1-2)
Turn
the VOLTAGE SELECTOR located on the rear panel with a screwdriver until the correct voltage is
indicated.
2) Cycle Conversion
Cycle conversion
is
not necessary since HX-R5 and
GX-R6
uses DC motors.
